A Background Level of Oxygen-Containing Aromatics for Synthetic Control of Carbon Nanotube Structure

摘要

The addition of a background level (～ 100-200 ppm) of water into the growth ambient has shown to dramatically improve the activity and lifetime of catalysts to synthesize vertically aligned single-walled carbon nanotube (SWNT) forests ("Super-growth"). Based on the fundamental understanding that water reactivates catalysts by the removal of a carbon coating,recent work showed that essentially any material containing oxygen could replace water as a "growth enhancer."
